4. the accuracy of the relevant components: in the case of a tight fit between the bearing ring and the bearing housing or the drive shaft, the bearing ring may be deformed in accordance with the shape of the adjacent components. If deformation occurs, vibration may occur during operation.
The causes of noise generated by rolling bearings are more complicated. One is the wear of the inner and outer rings of the bearing. Due to this wear, the bearing and the housing, the bearing and the shaft are broken, resulting in the axis deviating from the correct position and generating an abnormal sound when the shaft is moving at a high speed. When the bearing is fatigued, the surface metal peeling off will also increase the radial clearance of the bearing to produce abnormal noise. In addition, insufficient bearing lubrication, dry friction, and bearing crushing can produce abnormal sounds. After the deep groove ball bearing wears loose, the cage is loose and damaged, and abnormal noise is also generated.
